Description

Traditional Chinese medicine composition and application thereof in preparation of medicine for treating blood sugar reduction
Technical Field
The invention belongs to the technical field of traditional Chinese medicines, and particularly relates to a traditional Chinese medicine composition and application thereof in preparation of a medicine for treating blood sugar reduction.
Background
Diabetes mellitus is a common endocrine disease which is mainly characterized by chronic hyperglycemia, glycolipid metabolism and protein metabolism disorder, and the pathogenesis of diabetes mellitus is mainly due to absolute insufficient insulin secretion and islet resistance. When insulin is insufficient, the serum glucose content is continuously increased and exceeds the reabsorption capability of the kidney, so that a large amount of glucose is excreted along with urine, osmotic diuresis is caused, the body is dehydrated, brain cells lose water, brain dysfunction can be caused to be coma, and because a diabetic patient has sugar utilization disorder, energy is generated by decomposing fat, and the generation of ketone bodies is increased along with the fat decomposition, so that diabetic ketoacidosis is caused. Research shows that oxidative stress is closely related to the formation of diabetes, and excessive free radical generation by oxidative stress can cause the functional damage of islet beta cells, insufficient insulin secretion and peripheral insulin resistance, induce the formation of diabetes, and cause various complications such as diabetic neuropathy, diabetic retinopathy, diabetic cardiovascular and cerebrovascular diseases and the like.
Most of the hypoglycemic drugs commonly used in clinical practice are chemically synthesized drugs (such as alpha-glycosidase inhibitors). The toxic effects of enteroglycosidases through inhibition of hyperglycemia are associated not only with prolonged elevated blood glucose, but also with the relative levels of postprandial elevated blood glucose. After entering the small intestine, the polysaccharides in the food are degraded into some oligosaccharides and disaccharides by amylase, and then decomposed into monosaccharides by alpha-glucosidase at the brush border of the small intestine to be absorbed into the blood. Competitive inhibition of small intestinal glucosidase therefore reduces postprandial hyperglycemia levels. However, these drugs can cause serious adverse reactions when taken for a long time, such as: nausea, vomiting, abdominal discomfort, and the like, as well as leukopenia, ketonuria, lactic acidosis, and the like, have limited applications. The research and development of natural antidiabetic drugs with high efficiency, low toxicity and low price for reducing blood sugar to relieve diabetic complications is a problem to be solved urgently in clinic. Therefore, the search of high-efficiency hypoglycemic drugs from plants becomes one of the key points of the research of antidiabetic drugs at home and abroad.
CN106924479A discloses a traditional Chinese medicine composition for reducing blood sugar, which comprises the following traditional Chinese medicines in parts by mass: 16-20 parts of kudzuvine root, 16-20 parts of astragalus, 16-20 parts of hairyvein agrimony, 15-19 parts of mulberry leaf, 15-19 parts of tuber fleeceflower root, 15-19 parts of pine pollen, 14-18 parts of medlar, 14-18 parts of Chinese magnoliavine fruit, 14-18 parts of glossy privet fruit, 12-14 parts of cortex moutan, 12-14 parts of szechwan chinaberry fruit, 12-14 parts of tuber fleeceflower root, 10-12 parts of liquorice, 10-12 parts of green plum blossom, 8-10 parts of spina date seed, 5-7 parts of momordica grosvenori, 5-7 parts of honeysuckle, 3-5 parts of cyclocarya paliurus leaves, 1-3 parts of Chinese yam and 1-3 parts of szechuan lovage rhizome.
